The run capacitor maintains a continuous phase-shifted current to keep the blower motor running efficiently after start-up. When it degrades or fails, you'll notice symptoms such as the blower motor humming without spinning, the furnace cycling off on high-limit due to airflow loss, or the motor running sluggishly and overheating — all of which can cascade into costly motor replacement if left unaddressed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Single run capacitor | Factory OEM-matched MFD rating | 370V\/440V rated | Designed to Carrier factory tolerances (±3% MFD) for the PG8MAA048135AAJA platform\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine OEM Carrier part — not an aftermarket substitute.
